POULTRY-BROODER.

SPECIFICATION forming part of Letters Patent No. 790,898, dated May 30,1905. Application tiled August l1, 1904. Serial No. 220,410.

-To (L7/Z whom, it may concern.-

Be it known that I, ERNEST F. HoDGsoN, a citizen of the United States,residing at Dover, in the county of Norfolk and State of Massachusetts,have invented certain new and useful Improvements in Poultry-Brooders;and I do declare the following to be a full, clear, and exactdescription of the invention, such4 as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to poultry-brooders, and the objects of the sameare to provide a device of simple construction which may be easilymanaged by an unskilled person and which will maintain a substantiallyuniform temperature after once adjusted.

Another object is to provide means to prevent sudden drafts of air fromaffecting the temperature of the interior of the brooder or forpreventing any iiuctuation in the burner.

Another object is to provide means for heating the brooder by hot waterand arranging the various parts in such manner that access may be had tothe various interior parts of the brooder.

I attain these and other objects by means of the constructionillustrated in the accompanying drawings, in which- Figure 1 is aperspective view of a brooder made in accordance with my invention, thehinged roof or door of which is open to show the interior construction.Fig. 2 is a transverse vertical section of the brooder on the line 1 l,Fig. l. Fig. 3 is a front to rear central vertical section of the same.Fig. 4 is a plan view of the brooder with the water-tank and theexhaust-tube removed, taken on the line 2 2, Fig. 2. Fig. 5 is aperspectiveview of the water-tank and its connected parts, and Fig. 6 isa perspective view illustrating the manner in which the heater issecured to the removable sliding shelf.

Referring to the drawings for a more detailed description of theinvention, the numeral 1 designates ahousing or brooder frame, which maybe of any desired size and shape. This housing comprises a bottom orliooring 2, havinga lower air-compartment 8, provided with suitableair-holes 4 to admit air from the outside. A iiooring 5 is secured tothe side portions 6 at a suitable distance above the bottom, and saidfloor is provided with a central aperture 7 to admit the metalburner-tube 8, and a hinged roof or door 9 covers the entire structureorhousing. Extending from the front toward the rear at the bottom of thehousing is a recess l0, formed by means of the side strips 11 and thetop piece 12, the latter covering the rear portion of the recess 10 andhaving a recess or opening 18 to admit the burner-tube 8. Cleats 14 aresecured at the lower edges of the pieces 11 to form a support for asliding shelf 15, upon which the lamp or burner is secured. The lamp orburner is held in place upon the shelf by means of the pointed rods 16passing through ears formed at suitable points upon the lamp, and theshelf 15 may be slid out and in without danger of deranging the parts.

The metal burner-tube 8 is provided with a recess 17 upon the' frontside of such size as to admit the 'lamp-burner 18. A metal tube ordeiector 19 rests upon the ioor 5 and surrounds the burner-tube 8. Saiddeliector extends upward and terminates at a point a slight distanceunder the water-tank. A perforated cap 20 fits over the upper end of thedeflector 19 and serves to retard the heated air and to distribute ituniformly under the water-tank. The upper end of the burnertube 8 isprovided with a suitable number of perforations 21 for a purpose whichwill presently appear.

The water-tank 22, which is herein shown as of circular conformation, isprovided with a recess 23 to accommodate the upper end of theburner-tube 8, `said recess being slightly flared to conform to thetapered upper end of the burner-tube, as shown more clearly in Fig. 2.An vopening 24 extends centrally through the water-tank and communicatesat its upper end with a chamber 28, formed in a wooden top or cover 26.Within the chamber 28 a wire-cloth or foraminous screen or deiector 27is located. Covering the opening at the top of the chamber 28 is a blockor cap, to which is secured a pipe 26, said pipe extending-upward ashort distance as an elbow and thence extending backward andcommunicating with the outlet pipe or flue 29. The pipe IOO or iue 29 isprovided at its opposite ends with reduced tubular portions 30,journaled in the opposite side pieces 6 6 of the housing. By thisarrangement the pipe or elbow 28 may be lifted from its seat within thecap or block 31 in order that the water-tank and the board or hover 26may be removed or lifted from the burner-tube 8 to gain access to thebrooder-chamber 32. Secured to the outer ends of the reduced portions 30of the pipe 29 are wire-cloth screens 33, and secured to the sides 6 ofthe housing over the screens 33 are perforated boxes or caps 34, whichserve to prevent sudden drafts of air from affecting the temperaturewithin the brooder. Strips of felt 35 may be secured to the disk 26,said strips extending downward to the iioor 5 of the brooding-chamber.

In the back of the brpoder or other ,suitable parts openings may beformed and covered by wire-netting, glass, or mica, and a suitableopening or stairway may be provided to admit the chickens or to let themout, as desired.

. A screw-cap 36 extends through the hoverboard 26 to provide afiller-opening for the water-tank.

The operation of my brooder is as follows: When the burner is lighted,the heat passes upward through the perforations 21 and is retarded inits passage through the tube 24 by coming in contact with the lower wallof the recess 23, the heat thence passing upward through the pipe 24 andbeing again retarded and distributed by means of a screen 27 and thencepassing upward through the pipe 26 to the outlet pipe or flue 29 and outthrough the screen 33 and perforated box 34. The fresh air is permittedto enter the openings 4 and passes up around the heater tube 8, throughthe aperture 7 and inside the deiiector 19 out through the foraminouscap 2O,v

the perforations in said cap distributing the heat equally and radiatingit outward under the water-tank 22, as will be obvious upon reference toFig. 2. The deector 19 serves to insulate the heat at the center and toscreen the chicks from the burner-tube 8. Moreover,

the heat being distributed equally throughout the brooder-chamber, thereis no tendency for the chicks to crowd toward the center or around theburner-tube 8. Owing to the arrangement of screens at the ends of thepipe or iiue 29 any draft or gust of wind which might cause fluctuationin the burner and change the general temperature of the brooder-chamberis dissipated to a great extent owing to the fact that the openings 30are comparatively small while the screens 33 and the cap 34 exclude thegreater portion of the air at these points.

From the foregoing it will be obvious that my invention is ofcomparatively simple construction, may be easily managed, that the partsmay be easily reached for'repairs, and that an efficient and inexpensivedevice for the purpose is produced.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is*- 1. In a poultry-brooder, a burner-tubehaving a recess at its side to admit the burner, a foraminous top, awater-tank surrounding the upper end of the burner-tube and providedwith a central aperture, a chamber above said aperture, a cap coveringthe chamber, a pipe or elbow extending to the cap and communi-- catingwith the outlet-flue, said outlet-flue being pivoted at its ends Withinthe brooderhousing, substantially as described.

2. In a poultry-brooder, a burner-housing provided with cleats orsupports, ashelf adapted to rest upon said supports and provided withmeans for securing a lamp or burner thereon in combination with a metalburnertube having a recess in the side thereof to admit the burner of alamp, substantially as described.

3. In a brooder, the combination of a burner, a burner-tube having aforaminous top, a water-tank having a recess to fit the top of theburner-tube, a screen or deiector surrounding the burner-tube within thebrooder-cham ber and provided with a perforated cap at its upper end,substantially as described.

4. In a brooder a hot-water tank, a wooden cap to which the tank issecured, a central aperture in the cap, a cover for the aperture, amovable pipe passing through the cover, in combination with a burner andan outlet-flue pivoted within the brooder-walls,substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
